Dear Marcus
On May 6th I had occasion to do business with your company.
This is just a note to let you know how pleased I was with the service I received.
In this day and age good customer service is often difficult to find, and I feel it is important that it be recognized.
Thank you for your commitment to good customer service and the care taken when sending off my parcel which I received this morning . Keep up the good work.
Sincerely,
Robert
